Find something on him that will change her mind.

I mean to say, if you could find out he's got a wife already. Or that he's taken all the gold out of his Gringott's account and put it in Bubotuber research. Or that he's a regular client at Mistress Firkin's. Something dodgy that would make her change her mind.

So why should you have to be there tonight? It's not as if he's thinking of marrying both of you.


Never mind, then.
